A+ question

Hello:

I was wondering if anyone has been successful in getting A+ 4.20
working on a 64-bit Linux or BSD on x86-64 hardware.  I can send out
bug re****ts, but if, like Flash, the community is aware this just
doesn't work for these operating systems, I don't want to waste
anyone's time.

I'm brand new to APL, and I'm hoping to use it on a proof-of-principle
project writing physics codes manipulating three- and four-dimensional
arrays.  I've been primarily looking at A+ and J because of cost and
licensing issues; ideally this will evolve past proof-of-principle
into a commercial product.  I'd welcome any comments comparing any APL
dialects, particularly those comments concerning speed, memory, and
compatibility with C family and scripting languages.

Thanks for any help.
